Sir Paul McCartney popped out on stage to wave to the crowd during The Pretenders' set at Glastonbury Festival.
As the band finished up on Saturday, frontwoman Chrissie Hynde went into the wings to hug the Beatles star, Paul.
The crowd got excited and chanted for him to appear on stage and he quickly gave in and showed up to give the crowd a wave.
The Pretenders provided a lot of surprises as they brought the Foo Fighters' Dave Grohl on for the end of their set.
Johnny Marr, from The Smiths, was also a surprise guest for the band.
Ahead of introducing him, frontwoman Chrissie Hynde said: “Glastonbury has so many memories but my favourite is seeing my guitar heroes.”
While some celebrities shocked fans with appearances on stage, others kept it lowkey on the park grounds to watch their favourite stars perform.
British radio presenter Vick Hope was seen on Saturday evening enjoying a drink with a couple of friends.
She looked stunning in a navy minidress decorated with jewels. Vick completed her look with stylish brown cowboy boots, jewellery and sunglasses.
In the VIP area behind Park Stage, stars including Matt Smith, Colin Firth and Anna-Taylor Joy were seen relaxing during the day.
The backstage VIP area was decked out with incredible decorations and statues and had endless space to sit down.
Its bar was made to look like a circus and was fitted with fairy lights to add to the already-lavish atmosphere.
Thankfully, people were protected from the blistering heat in the tents the bars and restaurants are housed in.
Meanwhile, Holly was seen at the festival on Friday when she arrived by helicopter.
Mum-of-three Holly was into the spirit of the festival and was spotted by fans standing in line in one of the huge bar queues in the VIP area.
The TV star appeared to be in a great mood as she waited with the other VIPs to get a drink inside the special section for celebrities and certain ticket holders, but eventually gave up on the lengthy queue according to one onlooker speaking to the Mirror.
